Well I thank you all, but nothing is working for me. I have tried the velocity at 50 (boy is that slow) and the force at 80, 85 and 90. It appears to be cutting quite well - ie. not tearing, but when I take it off the mat - it hasn't cut anywhere near through - so obviously a waste of time, because it just hasn't cut.
I have put a brand new blade in (albeit from my Gazelle and not one supplied by Blackcat). I will have to leave it now because for one thing I am getting hungry (ready for my supper lol) and another I am sooooo frustrated with it and just don't know what to do. I cut literally sit down and cry right now.
I notice that you use the click blade holder Christy - and I just have the regular blade holder - so not really sure how far out I should be extending the blade. I don't want to extend it too far, because of breaking it.
I want to be able to use my linen cardstock, but it just doesn't seem to be able to cut for me.
Anyway - please know everyone that I really, really appreciate all of your suggestions and help with this.
I am going to turn the machine off now, turn off my computer, sit down with a cup of coffee and relax.
I will try again tomorrow
